Over the years, one thing has been very hard to grasp for some people: the fact that people want smartphones with 4.0"+ screens. These 'some people' seem to believe that because Apple chose a 3.5" display, any display size that isn't 3.5" is wrong. Keep that in mind when you read Samsung's latest little communiqué: the Korean giant has sold (not shipped, sold) more than 5 million Galaxy Notes. Which has a 5.3" screen.

... a phone as large as the 5.3 inch note, but I really like my 4.5 inch Galaxy S II Skyrocket. Email, and web browsing are much easier than on the iPhone (can you say presbyopia). Screen size is sufficient to keep me on android and off of iOS, but I would likely be back on any iPhone with a +4 inch screen that came out.

I agree with the poster who said that AAPL was sticking with 3.5 inch because it maximized profit. The question is do you want a phone that maximizes AAPL's profit or your utility?

The market is changing, there is no longer a monolithic "smartphone" market. AAPL makes laptops in multiple sizes to fit the needs of multiple market segments. It will eventually do the same in the smart phone market.
